A mysterious ink-black journal leads to the Soul-Returning Inn. A knock at the door on a rainy night triggers a taboo, while blood talismans in the morgue and a blood moon over the well spread an eerie atmosphere. With an ink compass, the investigator probes the mystery of nine blood corpses. Green flies nourish corpses with blood, a cave maiden's ghost seeks lives, and a stone coffin in a secret passage conceals the secrets of mountain bandits. A water demon reveals its true form, while the Nine Sons Gang's dark arts seek to bring the dead back to life. A ghost marriage with paper figures and bones in the well expose a decades-old massacre. Every step leads deeper into a terrifying abyss. Within the Soul-Returning Inn, the curses of the dead intertwine with dark magic. A bone-chilling truth lies hidden in the mist, and all who enter are trapped in this maze of Chinese horror, with no way home.
